PROBLEM TO BE SOLVED: To provide a fundus photographing device, which allows quantitative evaluation using a fundus image.SOLUTION: The device includes: a fundus photographing optical system for obtaining a fundus image, including an optical scanning means which scans at least part of light emitted from a light source on the fundus of a subjects eye as a measuring light, and a light receiving means which receives light including reflected light thereof and a correction means which acquires scanning position information of the measuring light scanned by the optical scanning means, and corrects dislocation of scan length of the fundus image in each scanning position based on the acquired scanning position information.COPYRIGHT: (C)2012,JPO&INPIT【課題】 眼底画像を用いて定量的な評価を行う。【解決手段】 光源から発せられた少なくとも一部の光を測定光として被検者眼眼底上で走査させる光走査手段と、その反射光を含む光を受光する受光手段と、を有し、眼底画像を得るための眼底撮像光学系と、光走査手段によって走査される測定光の走査位置情報を取得し、取得された走査位置情報に基づいて,各走査位置における眼底画像のスキャン長のずれを補正する補正手段と、を備える。【選択図】 図6
